feat(editor): add "Open in new tab" option for link previews

- Enhanced `PreviewOptions.vue` to include a new "Open in new tab" button for link previews.
  - Introduced the `openLink` method to open the link in a new browser tab.
  - Added `OpenIcon` for the button to improve UI consistency.
  - New `href` prop added to handle link URLs dynamically.

- Updated `extractLinkParagraphs.js` to extract `href` attributes from nodes.
  - Ensures link previews include the necessary `href` for the "Open in new tab" action.

These changes improve the user experience by allowing quick access to link previews in the editor, streamlining navigation workflows.
